The sonographic findings of an intratesticular spermatocele occurring with seminiferous tubular ectasia are discussed. A literature review revealed that intratesticular spermatoceles are extremely rare. This uncommon finding, as well as the etiology and ultrasound appearance of epididymal spermatoceles, tubular ectasia, and intratesticular cysts, are included. Awareness of the appearance of these benign entities may eliminate the need for more invasive diagnostic procedures.
